We provide a simple theoretical study on the Dirac cone existing in the monolayer χ3 borophene. Owing to the lattice mismatch with the substrate, the borophene is known to be subject to a long-range perturbation. The Dirac cone of the free-standing borophene is thereby expected to be preserved or lost depending on the degree of the lattice mismatch. We explain their relation using a minimal tight-binding model.
